Question

The efficiency of a machine is 80 Determine the work done by a person using this machine to raise a load of 200g via a vertical distance of 3.0m use gravity=10m/s

Answer 1

Explanation:

We know that work done is defined as the multiplication of magnitude of displacement d and the component of the force that is in the direction of displacement. Work Done Formula. Work done via force (F) is equal to the change in kinetic energy.
